Cordless Vax vacuum shows code “F1” and suction is reduced; filter icon may also be illuminated.

Safety first: Switch OFF and remove the battery before removing filters.

• 1. Remove and inspect the pre-motor filter: Access it via the dirt bin or top cover depending on model. If it appears grey or caked with dust, it needs cleaning.
• 2. Clean the filter:
  • Tap gently over a bin to remove loose dust.
  • If washable, rinse under lukewarm running water until the water runs clear.
  • Allow to air dry completely for at least 24 hours.
• 3. Refit correctly: Ensure the filter is fully dry and seated flat in its housing. An incorrectly fitted filter can allow dust to bypass and trigger warnings.
• 4. Reset the reminder (if applicable): Some models clear the F1 code automatically after a successful run; others may require holding a specific button combination (refer to the user manual).

Replace the filter if it remains discoloured or damaged after cleaning.
